Recent archaeological excavations on Barrow Island and the Montebello Islands, off the Pilbara coast, have revealed different objects that suggest they were part of the construction of a coastal house attributed to the first humans in the area. Peter Veth, an archaeologist at the University of Western Australia, confirmed that they have found stone axes and that these were made earlier than originally believed.
Some of these artifacts date back to mid and late Holocene period, about 11,700 years ago, although yes different pieces of stone of about 15,000 years old have been found. Likewise, different pieces of ornaments decorated with indentations and perforated with holes have also been found, shell beads and fangs that date back some 30,000 years in time.
Other important findings have been the mangrove forests as well as remains of extinct endemic mammals of the area and different mollusks, which suggests that in this area the coast has not changed much in so many centuries. Among the remains of mammals are wallabies, animals that today are found in more southern areas.
After having carried out different analyzes on the soil sediments in the area, Veth ensures that these islands about 7,000 years ago were part of the Australian continent. He is currently excavating some caves on Barrot Island with Tiina Manne, another archaeologist very involved in the project. In their investigations it has been determined that these caves were populated by one or more individuals between 31,000 and 7,500 years BC.
Different studies were carried out on the sediments in the area with large sieves fitted with a 1-millimeter mesh, with enough space to detect and retain carbon and other fragments to be subjected to radiocarbon analysis.
Veth claimed that Barrow Island was a place where the ancient inhabitants had an eminently based diet of seafood, especially shellfish due to the large amount of shell and shell remains that have been found. Also, thanks to the many caves out there, many individuals could live without disturbing each other, which could reveal a certain level of community.
Research will continue to be carried out to find out more about each and every finding that has been found so far and what is expected to be found.
After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
